RE: Tropical Storm Dolly
Check this out: http://www.ssd.noaa.gov/goes/flt/t2/loop-wv.html
It looks like the center could be trying to relocate farther north. In the first advisory, the NHC had the center near 18.4, -82.2. In the loop, look around 20, -83.
Not really sure I'm seeing evidence of that given this particular product, but what this product is very proficient in demonstrating is the TUTT whirling across the Yucatan. There seems to be more torque energy to that feature than Dolly.
There's a couple of schools of thought on that.. One, if the TUTT continues to move off, it could actually excite an outflow channel along the western periphery of Dolly's upper levels... However, if Dolly continues to move WNW/NW in tandem with the TUTT's west displacement, then the net will be positive shear. It seems when looking at the deeper layer, at least for time being, the latter is taking place. But the situation obviously is continuously evolving so who knows where we will be with this overall construct 12 hours from now.
Having said all that...none of it really matters much until the interaction of Dolly with Yucatan can be accurately assessed. If Dolly does indeed pass over the land mass, what are we talking about then. Kind of makes much of this moot at that point
